(Grapevine, TX)  —  Police have identified two of the four teenagers arrested Friday after a gun was found at Grapevine High School.

Tavian Price and Christopher Bishop are charged with criminal trespass, terroristic threat, and possessing a firearm in a school zone.  Two juveniles were also arrested.  Their names haven’t been released.  It all started when a  student posted an image on Snapchat of an individual with a gun in his waistband in the Grapevine High School cafeteria.  The campus was placed into a lockdown while police searched the building.  The gun was found and secured by officers.

The school district posted on Facebook that one of the suspects was not a GHS student.  Extra counselors were on campus today to help students if needed.
